Yō's half-Italian first cousin who is an avid gamer and will often use her wily ways to get him to do what she wants. She is also a bento brawler known as the Beauty by the Lake (湖の麗人 Mizūmi no Reijin?) after eating a bento on a bench at a park next to a lake and ended up falling asleep there. She's well known for using chopsticks in battle. She often goes scouting out other bento brawlers and usually hangs out with Yō and Sen.
